We produce various of bridge expansion joints including modular expansion joints, finger type expansion joints, elastomeric rubber bridge expansion joints and asphalt expansion joints, they are used on highways and briges to reduce the vibration and pressure from the various of traffic tools when they pass through, in this way to protect the highways and bridges.
Product Description
Finger-shaped expansion joint is a packaged type expansion device an mainly applied to the device with the extension 20-320mm.This type of expansion joint mainly comprises of elastomeric strip fixed on and connects with two sides of joint and the whole of finger shape plate and moving finger shape plate that can fit together with racks.The fixed plate and moving plate connect to bridge deck by anchor parts.And the movement of moving finger shape plate achieves the extension and contraction of this type joints without longitudinal transion clearance.

Bridge expansion joint: In order to meet the requirement of bridge deck deformation, expansion joint is usually set between two beam ends, between beam ends and abutment or at the hinge position of bridge. Expansion joints are required to be free and reliable in both directions parallel to and perpendicular to the axis of the bridge. Vehicles should pass smoothly without jumping and noise. Rainwater and garbage and soil should be prevented from seeping into the blockage. Installation, inspection, maintenance and removal of dirt should be simple and convenient. At the place where expansion joints are set up, the railings and deck pavement shall be disconnected.
The function of bridge expansion joint is to adjust the displacement and connection between the superstructure caused by vehicle load and bridge building materials. Once the expansion device of skew bridge is destroyed, it will seriously affect the speed, comfort and safety of driving, and even cause traffic safety accidents.
